San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

How Do Wildlife Rehabilitators Deal With Rats?
Even though rats do cause a nuisance in homes, they also need to be treated humanely when indisposed. In a situation where you find a stray and injured rat in your home, the best thing you can do is to contact a wildlife rehabilitator to help evacuate the rat immediately. While waiting for the rehabilitator, you need to avoid any physical contact with the animal, as rats are often carriers of different kinds of pathogens and diseases.
Wildlife rehabilitators are licensed professionals that help to evacuate animals from people's home, treat them if they have health issues, and release them back into the wild. Unlike other animals, wildlife rehabilitators handle rats specially.
Since stray rats do find it very difficult to survive on their own if relocated into the wild immediately, the first thing wild rehabilitators do is to nurture the rats for days or weeks to ensure that they are in good health. To do this, the rats are introduced into a box filled with woodland debris to make them feel comfortable and are properly fed with good food. This nurturing process continues until the rats can survive on their own without the help of anyone.
After successfully nurturing them, the wildlife rehabilitator can then go ahead and release the rat back into the wild. The release of the rat into the wild is not just done indiscriminately. Wildlife rehabilitators look for areas with a possible place of shelter for the rat with an abundant source of food.
Wildlife rehabilitators make sure evacuated rats stand a chance of living. Therefore, don't hesitate to contact a wildlife rehabilitator if you have stray, injured rats in your home.
